Cells in the blood do not provide nutrients to the other cells of the body. The nutrients are in the blood plasma (liquid). These nutrient diffuse through the vessel wall and travel to the bodies cells in the interstitial fluid (the fluid around individual cells). The epidermis does not have blood vessel running through it, so the nutrient must pass from the dermis layer of cells.

What are the two things that are supplied to the body's cells from the blood?
All cells need oxygen and nutrients to carry out their activities and that is what blood delivers.
What process are nutrients distributed to the epidermal cells in dugesia?
In Dugesia, or planarians, nutrients are distributed to epidermal cells primarily through a process called diffusion. The gastrovascular cavity, which is a central digestive space, breaks down food and allows nutrients to diffuse into surrounding tissues, including the epidermis. This diffusion occurs because of the concentration gradient, with nutrients moving from areas of higher concentration in the gastrovascular cavity to lower concentration in the epidermal cells. Additionally, the extensive branching of the gastrovascular system facilitates efficient nutrient distribution throughout the organism.
What cellular structures are found in the epidermal cells of humans but not in epidermal cell of leaves?
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
Do epidermal cells from petunia stain with phloroglucinol?
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.
The more superficial cells of the epidermis become less viable and die what factors account for this natural demise?
We skin cells are made, they are made in the deep layers of the skin, the dermal layer. This layer of the skin has blood supply, and cells that are in the dermal layer stay alive just fine. However, as cells in the upper layer, the epidermis, die; the skin cells in the dermal layer gets, pushed up into the epidermal layer. In this layer of the skin, there is no blood supply. However, nutrients are still passed from the blood rich dermal cells to the epidermal cells. The problem occurs when the epidermal cell is pushed right to the top of the epidermal layer, where there is no blood supply and it is too far away from the dermal layer to get nutrients vie osmosis. The cells in the upper epidermis get no nutrients and therefore die. Epidermal cells also die, ironically, because of the substances that they produce, keratin. Keratin is secreted by all skin cells to make the skin tough, durable and waterproof. However the build up of this keratin in the cell, leaks out in the extracellular space (the area outside the cell) and starts to breakdown the membranes of the cells around them and the cells essentially end up killing each other.Epidermal cells die because of the loss of nutrient supply as they get closer and closer to the surface of the skin, and the buildup of keratin inside them that leaks out into the area outside the cells.Read more: Why_do_epidermal_cells_die
Epidermal cells are supplied with nutrients from blood vessels located in the?
Epidermal cells are supplied with nutrients from blood vessels in the
Where do epidermal cells get their nutrients?
Epidermal cells receive nutrients primarily through diffusion from the underlying dermis layer, where blood vessels supply nutrients. Additionally, some epidermal cells can also absorb nutrients from sweat and sebum produced by skin glands.
What are the two things that are supplied to the body's cells from the blood?
All cells need oxygen and nutrients to carry out their activities and that is what blood delivers.
What epidermal layer is closest to a blood supply?
The basal layer of the closest layer to blood supply. You do not have blood supply to the outer layers of the skin.
What two factors cause epidermal cells to die?
Low blood supply and low keratin cause epidermal cells to die. Epidermal cells make up the epidermis, the outer layer of the skin covering the exterior body surface of vertebrates.
The cells of the heart are supplied with blood via the?
The cells of the heart are supplied with blood through the hearts own artery. The artery that supplies the heart blood is known as the coronary artery.

What does blood bring to the cells?
blood brings oxgen and nutrients to cells
what part of the blood cells carry food nutrients and oxygen to all cells?
The blood plasma contains the red blood cells which carries the food nutrients and oxygen to all the cells.
Do epidermal cells from petunia stain with phloroglucinol?
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.
Why do the epidermal cells have had there edges folded over?
The folds on epidermal cells, called microvilli, increase the cell's surface area for absorption and secretion. This increased surface area allows for more efficient exchange of molecules such as nutrients and waste products with the external environment.
